Methods have been developed for producing atomic hydrogen in the liquid helium temperature range, and also below 0.5K. These low temperature techniques provide opportunities for substantial improvements in polarized proton ion sources and related devices. Among the most dramatic of the new...
The possible use of optical pumping to produce beams of polarized H -; ions is discussed. The proposed H -; ion source involves H + ions incident on an optically pumped target where they pick up a spin polarized electron in a high magnetic field. The fast H 0 atoms formed pass diabatically...
This paper reviews the basic principle of atomic beam stage for polarized hydrogen ion sources. The problems of the forming, the spin states separation, and the focussing of neutral atomic hydrogen beams are discussed. It is shown that substantial improvement of the intensity and the density of...
Methods of increasing the intensity of H↘; -; beams are considered including microscopic quenching, fast spin–axis reversal, and ECR sources.(AIP);
A polarized atomic hydrogen beam target has been developed at CERN to be used as an internal target for the CERN‐SPS. (AIP);
The depolarization resonance in the KEK 12 GeV synchrotron is examined using the idea of spin‐flip. (AIP);
The technique of producing spin‐polarized beams of ; H -; and D -; ions by the Lamb‐shift method is reviewed. Maximum useable beam intensities are shown to depend on the flux of metastable H; 0 (2S) or D 0 (2S) atoms which can be obtained with a useable beam emittance. Factors limiting this...
Negative hydrogen ions can be produced a) in hydrogen plasmas, b) by particle scattering or desorption from low workfunction surfaces and c) by electron capture processes of protons or neutrals in a charge exchange cell.
The magnets and dynamics involved in the production of atomic beam by nozzles are discussed. (AIP)
